High efficiency and endless hot water are a great combination! Available in both natural gas and propane, certain rebates may apply. No need for a chimney with these units as they exhaust and intake air from the outside. These come in both condensing and non-condensing styles. Condensing units are more efficient, and typically offer more hot water while non-condensing typically are less expensive but less efficient. In either case, you only pay for your hot water usage—no gas wasted keeping a tank hot all day!

These units are your standard water heater. They come in different sizes, but the most typical are the 40 and 50 gallon tanks. Natural gas or propane heats up the water and maintains temperature 24/7. These are usually the least expensive option to swap if it was existing to begin with. These are the least efficient units, however. They are also available with electric feed!

This water heater is a storage tank similar to the gas fired or electric water heaters. However, this system is heated up by a boiler. Typically, a boiler heats up your house and the tank—one unit doing both. However, sometimes in certain instances like commercial kitchens, you have a dedicated boiler heating up just an indirect water heater.
